Apolipoproteins Profile, Serum

Apolipoproteins are proteins attached to lipids. They transport cholesterol through the blood. There are two types of Apolipoproteins, that is Apolipoprotein A and Apolipoprotein B. Attached mainly to the HDL, which is good cholesterol, Apolipoprotein A helps to remove the bad cholesterol from our blood. Apolipoprotein B on the other hand is attached to LDL, which is a bad cholesterol. It causes heart disease.

Lipoprotein A also attaches to LDL and gets deposited in the arteries leading to clogging and plaque formation. Apolipoproteins Profile is a blood test to measure Apo A1, Apo B, ratio apo B/A1, and lipoprotein Lp(a). These are predictors of cardiac risk or heart disease. Lipoproteins are soluble proteins that help in transporting fat and lipids in the blood. Apolipoproteins are a major part of lipoproteins that help in the regulation, solubility, and maintaining the structure of lipoproteins.

Apolipoproteins also help in metabolizing (breaking down) lipids and forming high-density lipoproteins, known as good cholesterol. It helps in eliminating the bad cholesterol (LDL) from the body and maintaining optimal cholesterol levels.
